Abstract (en)

A metal-working water or a metal-working composition which has excellent cooling and lubricating properties and does not exert a harmful influence on the environment. A metal-working water containing sodium ion and one or more kinds selected from the group consisting of fluoride ion, hydrogencarbonate ion and silicon and being adjusted to pH 6.0 to pH 10 can be used as a substitute for a conventional cutting oil. A metal-working composition including a metal-working water with such additive as a rust-preventive agent and being adjusted to pH 6.0 to pH 10 can also be used.
